sd_bus_message_copy — Copy the contents of one message to another
#include <systemd/sd-bus.h>
int sd_bus_message_copy( | sd_bus_message *m, |
sd_bus_message *source, | |
int all) ; |
sd_bus_message_copy()
copies the contents from
message source
to m
. If
all
is false, a single complete type is copied
(basic or container). If all
is true, the contents
are copied until the end of the currently open container or the end
of source
.
On success, this call returns true if anything was copied, and false if there was nothing to copy. On failure, it returns a negative errno-style error code.
Functions described here are available as a shared
library, which can be compiled against and linked to with the
libsystemd
pkg-config(1)
file.
The code described here uses
getenv(3),
which is declared to be not multi-thread-safe. This means that the code calling the functions described
here must not call
setenv(3)
from a parallel thread. It is recommended to only do calls to setenv()
from an early phase of the program when no other threads have been started.
